Check the sticky note for Entry Clearance experiences of members.

There are many from India too.
BTW, where you are applying? People have different experiences in different BHC offices. Mumbai is cool(personal experience) compared to Delhi and Chennai offices(Other members opinion).
Documentation is fine. Experience letters and HSMP approval note are important. IT returns doc is also important (Even last year statement works)
Will there be any impact if we show high worth of property, when applying for migration? (May be you can setup your own office over there

)Seniors comments are needed on this.
'Have you been refused visa to U.K. ?
You can strikeout this option. Answer is No. Any subsequent
approval after a refusal is not considered as "Refused to enter".
Where did you get the form? Better fill the form you got from the VFS office.
Hope this info helps you.
